Elasto-Plastic FEM Models Explain the Emplacement of Shallow Magma Intrusions in Volcanic Complexes

A. Bistacchi[1]
[1]Università degli Studi di Milano Bicocca, Milano, Italy

We present numerical models and field data that aid understanding of volcano-tectonic processes related to the propagation of inclined sheets and dykes under a stress field resulting from the inflation of a shallow magma chamber. Structural field data from the classical Cuillins cone ... Per saperne di più

Impact Assessment of Hydrologic and Operational Factors on the Efficiency of Managed Aquifer Recharge Scheme

M.A. Rahman[1], P. Oberdorfer[1], Y. Jin[1], M. Pervin[1], E. Holzbecher[1]
[1]Department of Applied Geology, Geoscience Center, University of Göttingen, Göttingen, Lower Saxony, Germany

Due to increased demands on groundwater accompanied by increased drawdowns (ca. 2-3 meters/year), technologies that use alternative water resources have been suggested for Dhaka City, Bangladesh. Preliminary studies show that managed aquifer recharge (MAR) would help in optimal use of ... Per saperne di più

Coupling Heat Transfer in Heat Pipe Arrays with Subsurface Porous Media Flow for Long Time Predictions of Solar Rechargeable Geothermal Systems

P. Oberdorfer[1], R. Hu[1], M. Azizur Rahman[1], E. Holzbecher[1], M. Sauter[1], P. Pärisch[2]
[1]Applied Geology, Geoscience Centre, University of Göttingen, Göttingen, Germany
[2]Institute for Solar Energy Research Hameln/Emmerthal (ISFH), Emmerthal, Germany

An increased share of renewable energies is regarded as an integral part of a strategy towards a sustainable future. With regard to the heat supply sector this may be achieved using solar thermal collectors or heat pump systems with borehole heat exchangers. During the last years solar ... Per saperne di più

Electromagnetic Field Computations for Saturated Porous Media

S. Cambon[1], I. Bogdanov[1]
[1]CHLOE, Bâtiment UFR Sciences et Techniques, Pau Cedex, France

Non-conventional hydrocarbon resources become more and more challenging object for energy producing companies throughout the world. Being already known and long-explored method, the electromagnetically (EM) assisted recovery constitutes a promising idea of technology for deposits of such ... Per saperne di più

Numerically Generated g-functions for Ground Coupled Heat Pump Applications

J. Acuna[1], M. Fossa[2], P. Monzó[1]
[1]KTH Energy Technology, Stockholm, Sweden
[2]Dime, University of Genova, Genova, Italy

Ground-coupled heat pumps (GCHP) are successfully installed since at about 20 years in many countries to fulfill space conditioning requirements in building applications. In most cases the heat pump is connected to a system of vertical ground heat exchangers (as illustrated in Figure 1) ... Per saperne di più

Numerical Simulations of Radionuclide Transport through Clay and Confining Units in a Geological Repository using COMSOL

[1]Swiss Federal Nuclear Safety Inspectorate (ENSI), Brugg, Switzerland
[2]Kantonsschule Solothurn, Solothurn, Switzerland

Introduction: The sectoral plan that defines the procedure and criteria of site selection for deep geological repositories for all categories of waste (high-level and low- and intermediate-level waste) in Switzerland started in 2008 and will last for about ten years. ENSI (Swiss Nuclear ... Per saperne di più

Simulation of Pumping Induced Groundwater Flow in Unconfined Aquifer Using Arbitrary Lagrangian-Eulerian Method

Y. Jin[1], E. Holzbecher[1], S. Ebneth[2]
[1]Department of Applied Geology, Georg-August-University, Göttingen, Germany
[2]Hoelscher Dewatering, Haren, Germany

A novel numerical method characterizing groundwater flow in unconfined aquifer is demonstrated.
